i have a quetion ,how will knowing the sum and the product of the roots help me later in more advanced math or phisics just curious if its just their like just pure math or does it have an accuall use in physics or calculas maybe something of real value or maybe a use in like a more advanced math idk

I found my way here because I was stuck on a Complex numbers (Ext 2 Math) question and it was asking about the sum and product of roots. The more you know the more you are able to apply it to "new" situations

what if theres 3 or more roots???
@SankalpaSatyal10 ай бұрын
A quadratic can only have a maximum of 2 roots because ax^2+bx+c=0 is factorised as a * (x-r1) * (x-r2) = 0. You need higher degree polynomial for 3 roots. A cubic ax^3+bx^2+cx+d=0 factorized as a * (x-r1) * (x-r2) * (x-r3) = 0 has 3 roots and for it you have r1+r2+r3=-b/a, r1*r2 + r2*r3 + r1*r3 = c/a, r1*r2*r3 = -d/a

Your second step of multiplying a to (x-alpha) (x-beta) is syntactically and mathematically wrong. You cannot simply do it without giving a mathematical justification. While the end result is the same, the correct method is to first convert ax^2+bx+c=0 to the form x^2+(b/a)x+(c/a)=0. Then equating to the roots.

I was thinking the same thing but I guess it makes sense as if you had something like (2x + 1)(x - 5) and you factored out the 2 you would get 2(x + 1/2)(x - 5) and the roots would be -1/2 and 5, while if it was it the other form one of the roots would be mixed up with the 2. I don't know if that makes sense or not...
